SPC043 50.8 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The SPC043 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of -250 mm, making it ideal for applications that require a negative focal length. The lens is uncoated, providing a clear, unaltered view of the light spectrum.
The lens's geometry is meticulously designed, with a thickness of 4.8 mm at the edge and 2.5 mm at the center. The inner and outer radii are both zero, indicating a uniform curvature throughout. The back focal length is -251.71 mm, a slight deviation from the focal length due to the lens's concave shape.
The lens is made from UVFS material, specifically UVFS Mal-1965. This material is well-suited for applications in the 589 nm wavelength range. The lens's base shape is circular, ensuring uniform light distribution and minimal distortion.
